i'd guess it's a touch too soft for their liking. i bet they do a lot of training in a boost shoe but for race day, the firm stuff is probably what they like.

Nobody but you are saying that. Those guys were popping off that pavement today. It looked to be the BOOST, or even a special production model of even bouncier BOOOOOST!
That boost crap is silly, just like people who think bouncy tracks will make them go faster, when hard tracks are fastest. Trying to produce a trampoline effect just screws up your biomechanics.However,
IAAF Competition Rule 143.2 says
Athletes may compete barefoot or with footwear on one or both feet. The purpose of shoes for competition is to give protection and stability to the feet and a firm grip on the ground. Such shoes, however, must not be constructed so as to give an athlete any unfair additional assistance, including by the incorporation of any technology which will give the wearer any unfair advantage. A shoe strap over the instep is permitted. All types of competition shoes must be approved by IAAF.
So if that boost shit really did work, then it's illegal and IAAF would have to ban it and erase the record, which it damn well should in that case.
You agree the Newton lugs were a spring-like flex-beam introduction, yes? Such a device could possibly benefit one runner more than another; if you have a basic understanding of mechanics, you would understand the tuned restitution is mass dependent. Throw in various foot-strike mechanics and it becomes a much more complex issue, to prove or disprove otherwise.
I consider it not unreasonable that one major way for the benefactors (e.g., the Adidas sponsors) to abet their R&D would be to distribute their latest laboratory shoe incarnations to their stable of thoroughbred Kenyan athletes, for them to actually try out various models on pavement, whereby the stopwatch is the 'proof-in-the-pudding'.
And as an additional thought for reconsideration, they even let the blade-runner compete in the normal Olympic Games.

That's Tim Hutchings, not Larry Rawson.
It seems like a everyone is suggesting that the Adidas Boost material somehow makes you run 30sec faster in a marathon...
P.S. They definitely wore boost.

Thanks for the correction. Hutchings does an entertaining job.

Nice link, corroborating what we are suggesting here. And he agrees putting more of the BOOOST material up under the fore-foot could be an interesting improvement.

But then, if this stuff really does benefit in energy return trampolining, Adidas has to contend with maybe it being too obvious to the point that their competitors might try to get them outlawed. Spira took that as a badge of honor for marketing purposes, but they were a much smaller market, unlike the much bigger Adidas BOOOST campaign.
I have seen Spira lab test results to verify their outlandish energy return claims. Turns out it is total bullshit. The springs have very high energy return but all the shit built around them to make them actually runnable negates all the benefit, and they are actually worse than most good foam running shoes.
As Runners World confirmed:
"Martyn Shorten also used a drop test to confirm that the Adidas shoe produced more energy return than any of the 800 other running shoes in his database. But this is a machine and materials test, not a test of runners who are running. No one really knows what energy return means to runners, if it means anything at all."
Sub 2 project .... believe.
Can you share the report you referenced about the Spira shoes?
Damn, I was disappointed with the Boost performance results. Guess it's all marketing.. oh well.
Why did Mutai wear a different shoe (non-Boost) than Kimetto?

Terrible troll, so you either
(1) work for Adidas to bring more attention to the Boost (the shoes may deserve the attention, since Mutai and Kimetto were bouncing off the roads in them);
(2) work for the competitors, trying to discredit the shoes;
(3) you are actually serious, and don't realize Kimetto in the picture has changed out of his racing shoes.
